Frequently asked questionsCommon questions answered

These answers explain common case converter tasks, expected input formats, and edge cases so both visitors and search engines can understand what this tool does.

What is title case?

Title case capitalises the first letter of each word. It is commonly used for headings, article titles, and proper nouns.

What is sentence case?

Sentence case capitalises only the first letter of the first word and leaves the rest lowercase, matching standard sentence formatting.

What is camelCase?

camelCase removes spaces and capitalises the first letter of each word except the first. It is widely used for variable and function names in JavaScript and other languages.

What is snake_case?

snake_case replaces spaces with underscores and lowercases everything. It is common in Python, database column names, and file names.

What is kebab-case?

kebab-case replaces spaces with hyphens and lowercases everything. It is standard for CSS class names, HTML attributes, and URL slugs.
